OIL-STOVE.

Specification of Letters Patent.

Patented May 11), 19211.

Application filed August 25, 1920. Serial No. 105,868.

T 0 all whom it wm g cor'iccrn Be it known that LTHoMAs EDWARD Coon, a citizen of the United States, residing at Dallas in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

This invention relates to certain new and useful improvements in oil stoves and pertains more especially to oil stoves which embody movable burners so that the latter may be raised or lowered to increase or decrease the intensity of the flame and to extinguish the latter.

The primary object of the invention is to provide improved means for effecting vertical and uniform movement of the burner and to provide means which can be easily and quickly operated and which will remain stationary in any position to which it is or may be moved.

A further object of the invention is to provide an improved mounting for the burner which latter functions in a dual manner namely to provide a multi-point mounting for the burner and at the same time one in which oil is fed through the several points from the reservoir to the burner, thus assuring a constant, uniform and reliable oil "feed tor the latter.

Further and other objects will be later set forth and manifested in the course of the following description.

Briefly, the invention proposes diametrically opposed hollow slides upon which the burner is mounted and through which oil is fed to the latter, and a single member which is connected to the burner and which engages spaced and oppositely disposed cam surfaces to effect a true horizontal movement of said member and therethrough the burner.

Referring to the drawings, Figure 1 is a side elevation of the invention.

ent invention a pair of vertical pipes 1 are employed. leading upwardly from a horizontal pipe 2, the latter connected to a vacuum feed oil reservoir or tank 3. Suitable brackets 41 are rigidly mounted on the pipes 1 and support a drum-like base 5 having air openings 6 therearound.

The upper ends of the pipes 1 are provided withstufiing boxes 7 having the usual glands and slidingly receive therethrough vertical pipes 8 upon which the burner 9 is mounted. A rod 10 is secured to and de pends from the top of the burner B and is braced by a bridge or strut 11, the latter secured at its ends to the pipes 8 and at its center to the rod.

The rod 10 carries an exteriorly threaded sleeve 12 upon which is mounted an interiorly threaded sleeve 13, the latter having a smooth cylindrical part 1&, with a circular flange 15 at the upper end thereof. A nutlike formation 16 is provided on the sleeve 13 to allow gripping with a wrench and consequently movement of the sleeve along the length of the sleeve 12. The sleeve 13 is further provided with an exteriorly threaded lower end portion 17. A rotatable collar or ring-like member 18 is mounted on the cylindrical part 14; and has oppositely disposed threaded apertures 19 in which latter rods 20 are threaded. One of the rods may be provided with a suitable handle 21 as depicted in the drawings. The collar 18 abuts the flange 15 at one end and at its opposite end is held against downward movement by a nut 22, the latter engaged. by a jam or lock nut 23. If desired an additional lock nut 24k may beused and is applied to the lower end of the sleeve 12 to abut the nut 23.

The upper portion of the drum 5 is formed with a pair of oppositely disposed cam-like slots 25 which incline downwardly in opposite directions and from diametrically opposite points at the top part of the drum. These slots are of sufiicient width to receive therethrough the respective rods 20. The drum 5 may bear suitable indicia such as Out, High and Light as illustrated.

In operation, it will be understood that the oil flows from the reservoir through pipe 2, into each of the vertical pipes 1 and from the latter into the circular trough 26 of the burner, where it saturates the usual asbestos or other ring 27 and is ignited. When the rods 20 are opposite index Out the burner is at its maximum elevation and any oil in the trough drains out therefrom. When the burner is to be used, the rods 20 are moved down to Light which movement is efiected which will cause rotation of the collar 18 and therethrough similar downward movement of the other rod 20. In this movement it will be seen that the burner is guided at two points by each of the pipes 8 and the collar 18 being located centrally between these points a perfectly balanced action of the parts will obtain. This movement causes flow of the oil into the burner and the oil is then ignited. The rods 20 are then given upward movement to lie opposite High at which point the flame has its maximum of intensity. It is particularly to be observed from the foregoing that the rods 20 are automatically held at any point along the lengths of the cam slots by the walls of the latter and through friction resultant from the weight of the parts imposed upon the rods. The adjustment of the burner thus is such as to in volve an automatic look, so to speak, since some little pressure is required to move the rods from any position which the same may occupy.

It will also be noted that the two rods act as a single one and that two cam surfaces act to effect movement thereof and to automatically hold the same subsequent to the completion of such movement.

The device is free of all movable parts requiring lubrication excepting as to the collar 18, and provides a simple and positive action and the elimination of all movable parts subject to derangement.

What is claimed is:

1. In an oil burner, a feed pipe having vertical branches, a burner having depending inlet pipes slidably connected to the respective vertical branches, a member having oppositely'disposed inclined cam slots, a member extending through each of the cam slots, and means to movably connect the last named member to the burner whereby upon movement of the last named member through the cam slots the burner will be correspondingly raised or lowered.

2. In an oil burner, a vertically slidable support for the burner, a pair of spaced op positely inclined cam surfaces, means including rod-like parts engaged with the respective cam surfaces to raise and lower the burner, and means to turnably support said first named means from the burner.

3. In an oil burner, a pair of spaced vertical slidable supports for the burner, oppositely inclined cam surfaces on opposite sides of the supports, raising and lowering means for the burner including parts engaged with each of the cam surfaces, and means to turnably connect said raising and lowering means to the burner at a point substantially central of the space between the vertical burner supports.

4. In an oil burner, a feed pipe having vertical spaced branches, a burner having depending feed pipes slidably connected to said branches, a hollow dome-like base supported on the branches and having diametrically opposed and oppositely inclined cam slots therein and arranged on opposite sides of the branches, a rod depending from the burner and rigidly connected thereto, a collar turnable on the rod, means to hold the collar against movement lengthwise of the rod, and a pair of oppositely disposed rods rigidly connected to diametrically opposite points on the collar and engaged through the respective cam slots to raise and lower the burner.

In an oil burner, a feed pipe, a burner, a pair of spaced hollow oil-receiving supports for the burner connected to and communicating with the feed pipe and the burner, a pair of cam surfaces on opposite sides of the supports, and means movably secured to the burner between the supports and engaged with each of the cam surfaces to raise and lower the burner.

In testimony whereof I affix my signature.

THOMAS EDWARD COOK.
